ABSTRACT:
Disclosed herein is a muffler of a linear compressor. In the present invention, a center of an entry pipe of the muffler is in line with that of an inhale port of a piston. Therefore, a flow loss occurred when fluid is inhaled into the inhale port from the entry pipe can be reduced, and inhale efficiency can be improved. Furthermore, the plurality of inhale ports is eccentrically disposed in a front of the piston, and each center of the plurality of entry pipes is formed to be in line with that of the inhale ports. Not only the center but also the number of the inhale port and the entry pipe are agreed, on this account, the flow loss can be decreased and the inhale volume can be increased.
